When I was younger and my grandpa had been gone for many years, my youngest brother notice a cardinal always at the back door year after year. My mother told him it was grandpa. Well I recently lost my father and I needed a sign that he was okay,one I would know. The next day, which was a sad day I saw a cardinal sitting in a tree right in front of me. That cardinal sat for as long as I sat there. It must have been 45 Minutes. Now every time I am feeling blue I notice a cardinal. I choose to believe that it is my dad giving the sign that I would know. Just like I asked for.
